GUNS MODIFY M2 / M3 Style Sight Protector for M2 / M3 Style Dot Sight

The best and the last protection you will ever need for your dots. I also have one for a Micro T1 style dot. Very easy to mount (it may require a bit of force) but once it is on you can forget about it. Very high quality a durable material and a clear lens protection that you won't even notice it.
